Driverless electric shuttle being tested in Vegas

LAS VEGAS — There’s a new thrill on the streets of downtown Las Vegas, where high- and low-rollers alike are climbing aboard what officials call the first driverless electric shuttle operating on a public U.S. street.

The oval-shaped shuttle began running Tuesday as part of a 10-day pilot program, carrying up to 12 passengers for free along a short stretch of the Fremont Street East entertainment district.
